There were likely no problems within your equipment, until after that static-discharge zap. That huge DC transient could certainly fry voicecoils! Probably just the woofers are damaged, but there may be other issues (that buzzing sound coming from the mids, even after replacing the PA) you may now have phono stage, or more likely have preamp issues too? May need to check out the speaker crossovers & mids too. Hopefully the tweeters are probably OK. The warning indicator on the PA may indicate internal damage, or at least blown rail fuses.
In the future you'll need to remember to turn down the volume control fully before working with the turntable. My own TT also builds up quite a static charge sometimes; makes quite a zap when removing a record from the platter. I've since grounded the spindle carrier directly to my preamp's grounding-post, via a separate wire from the tonearm ground.
